ding xian急~~谢谢各位高手,或者能提供模型说明.小弟先感谢了
有专门的说明文档
pcml 是与沟道调制效应有关的参数,但是不知道与lambda是什么关系。
我找了好几天了,没有相关的文档,我开始也觉得pclm是沟道调制系数,但从仿真结果上发现不对
berkery bsim3v3 可以看一下
各种不同的模型,参数用的名称代码还是一样的,可以参照一下别的可以下到文档说明的对照看。
同问
沟道调制系数一般变化的,电路设置的参数不同,沟道调制系数也不同,所以一般模型里是没有的吧,你可以大致仿一下,然后估算它的范围?
不知道这种说法是否正确?
嗯,我一般也是这么做,不过一般用不上。只能大致计算用。
lamda随w/l变化很大,随电压偏执的不同变化也很大。感觉没有多少意义。
